[09:21:45] Alexandre Santerne: Thanks for following us ! End of the night. Time for astronomers observing #PaleRedDot to sleep.
[09:21:03] Guillem Anglada Escudé: anything you want to add to your audience?
[09:18:18] Guillem Anglada Escudé: ok. Yes. I’ll prepare a clean timeline later. Hopefully twitter comes back online so I can pull your text as well
[09:16:05] Alexandre Santerne: seeing during the observation: 1.3” – 1.4″
And the first spectrum!
[09:08:14] Guillem Anglada Escudé: yeah. Its good!
[09:08:04] Alexandre Santerne: snr@650nm = 65.3[09:07:46] Alexandre Santerne: exposition ended
The image on the right is Proxima on top of the optical fibre at the telescope focus. The same fibre goes all the way down to the spectrometer, which sits in the basement on top of the bedrock and lots of concrete
(not much to do for next 20 min, which is the exposure time…)
[08:49:51] Alexandre Santerne: flux level ~ 30%
[08:49:48] Guillem Anglada Escudé: cool
[08:46:41] Alexandre Santerne: exposure started
[08:46:36] Alexandre Santerne: focus ok
[08:43:07] Alexandre Santerne: checking focus
[08:39:31] Alexandre Santerne: pointing telescope …
